SN Field Concern Action concluded Further Actions planed Resp Trgt date Remarks
Hyd malfunctioninng -control valve/Release & releif valve
Magnetic stainer to be put at Suction line
Sample procured, new design under development R&D 10.12.14 Proto will be ready by 17.11.14
Release& release valve qualityTo study setup and implement the same, either on vendor end or QA
QA 17.11.14 IT was concluded that testing facility at vendor end and at QA shall be same
CRE 1200 kg to be implemented UNDER IMPLEMENTATION Matl/QA 2W Feb'14 NG Models are being made with CRE only
2CA guide seal leak-post modified
Design needs improvement in SC tractors
ECN Implementation Matl/QA 10-12/11.14 Only Modified CA Guide to be assemble with immediate effect
3Diff hsg breather leak / ineffective breathing action
Integrated breather to be used - existing breather is in effective
New breather under trails, prelimnary trial is OK R&D 2w Dec'14 3dec 10 pcs
Pre loading process to be standarized
To ensure the pre loading process as per SOP QAcontineous
processCutt off no - QAD-5518648
Wheel thrown away after brg breakage- spacer size to be increased
Dim 53 changed to dim 40 mm to protect wheel comes out - to be revisited - to be implemented
Matl/QA 20.11.14implemented after consumption of stock 125 tractor
5RV assy - control valve mtg stud leak
Control valve mtg face Sq ness / O ring dim & material / groove depth/widh to be checked
Analysis of failure was studied, porousity problem apeared
QA/R&D New design concept drawn, trial by 2w Dec'14
6Hyd pump adopter leak from O ring
CFT to study the problem at assy line
Hyd Adopter design modified Mat/QA 18.11.14 Action taken details with cutt off nos awaited
Tendom pump with 10.9 CC to be explored Mat/R&D 4w Nov'14 Comprehensive action by Nov 14
Failed sample with proposed action sent to Xinchai on 14.8.14 - corrective action awaited
PC 3.9.14Modifed sample expected in Nov 14 from Xinchai
Spare parts stock to be purchased from Allena only Spareparts 3.9.14 Drawing already approved
Radiator to be protected by providing net gril till improvement from Xinchai in water pump get implemented
Proposal along with proto photo re sent to RD by PC- trial to be done
RD 6.9.14
Coolant bottle mtg location to be changed
New location drg & proto ready by month end- trial by RD 5.11.14
5 saples received, but not approved yet, pending with R&D
NRB failure understodd due to procurement from unauthorised source
To ensure procurement of NRB 2016 from quality source Matl NAAction already taken by quality source of bearing
NRB 2016 to replaced with Sintred bush
NRB to replace with cintred bush - further study to be done
RD NA Dropped yet as action taken as above
Failed items to be analysed metallurgically - report to share & spectroscopic analysis to be done
QA 3.9.14 Ok
Radiator( high value) - conseq failure a) water pump shaft
broken b) coolant resorvoir mtg at radiator breakage
CFT observation is shaft of water pump breakage subsequent to
bearing failure - brg is of inadequate strength
9Plannet carrier (NRB 2016 fails & conseq teeth damage )
Spider kit strengthening to be explored -CFT analysed the failure

7Power steering hard < 1000 rpm with tendom pump
Tendom pump flow 8.5 cc / rev & AX series pump flow 9.0cc/rev - Drawing of M/s Bosch approved
4Hub brg - power steering - 30206 breakage

SN Field Concern Action concluded Further Actions planed Resp Trgt date Remarks
Oil starvation observed - Scoop to be added for better lubrication of Spider kit -ECN to be released
RD 17.11.14
Surface finish & cylindericity of BP shaft to be improved
ECN released - QA to submit report QA 3.9.14
11 Brake pedal Misaligned Brake pedal being received in pair paired brake pedal to be painted & fitment in set Done
12 Sealing screw ( drain plug - Gb) ERN -209 /31.7.13 released Sealing tape to be used Matl
13Battery Side shifting in AX series
K- series & NG series already have side batterry
Battery Side shifting in AX series to be done -ECN to release by 18th Aug -Implementation
Done Implemented
14Power steering tank leakfrom breather
In effective breathing OK , if oil level is upto bottom marks - either marks to be changed or bottle to be changed
QA 10.12.14 Intermediate action with low oil level
15Trumpet hsg - break from Flange
Low flange thickness & weaker strengthening ribbs wrt to compititors
Wall thickness increased from 20mm to 23+1 mm - sample received
Mal/QA 21.11.14 Price increase by 2kg per piece
16 Oil pressure switch Not working - post modified failure
Data for post modifed failure given - to be analysed QA
1Trcebility of major items wrt chassis no
To elliminate possibility of items mix up or claims agaisnt differrnt chassis no
List of major 20 items provided - traceability to be work out
R&D /QA
2Sticker on tractors how to operate tractor on different implement
to facilitate the customer to use appropiate gear & engine rpm - our eng rpm range is from 1800- 2300 rpm
mktg given the sample to R&D - to be work upon R&D /QA 1W Dec'14
NSD / 31.10.14
Other issues
explored -CFT analysed the failure on 6.8.1410
